Measuring Stairs with Turns
Measure each straight section and add them together to get your total length. For best results, measure from corner to corner where the walls meet.
Don’t worry about corner fittings or adjusting your measurements. We’ve already accounted for these in our calculations, so simply enter your total length as measured. For a full step-by-step walkthrough,
read our staircase measuring guide.
A turn is any point where the handrail changes direction, such as around a corner or changes angle.
Measure each straight section between the turns along the line the handrail will follow.
The calculator will add the correct corner fittings based on the number of turns you enter.

Plan The Right Handrail System For Your Stairs
Every staircase is different, so the right-hand rail parts depend on your layout.
The calculator helps you plan an internal handrail system for common staircase setups, including straight stairs, stairs with a landing, handrails around corners and turning staircases.
Whether you are replacing an existing handrail or planning a new one, it gives you a simple way to check what parts you need before ordering.
Works with common staircase layouts
-
Straight FlightFor stairs that run in one direction without a turn.
-
Quarter LandingFor stairs with a 90-degree turn, often described as an L-shaped staircase or stairs with a corner.
-
Half LandingFor stairs that turn back on themselves, often described as a U-shaped staircase or dog-leg staircase.
-
Single WinderFor turning stairs that use angled steps instead of a flat landing.
-
Double WinderFor staircases with two turning sections.
-
T-ShapeFor split staircases or more complex layouts.
